Direct Replacement Battery

The KingSener L17L3P61 is a new 11.58V 36Wh lithium-ion battery built for compatible Lenovo laptops. It matches the original part numbers L17M3P61, L17C3P61 and 81AK. The 3108mAh cell count restores factory runtime for daily work and study sessions.

Upgrade From Degraded Original

This unit replaces a worn or swollen factory pack that no longer holds a useful charge. The jump is worth it when the machine shuts down early, reports a battery fault or shows significantly reduced unplugged time. It returns the notebook to its designed mobility without changing the chassis or power brick.

Verify Model And Part Number

Confirm the exact laptop model appears in the supported list: IdeaPad 320S-13IKB, Yoga 720-12IKB, Yoga 330-11IGM, Flex 6-11IGM or Xiaoxin 7000-13. Cross-check the old battery sticker for part numbers 5B10N87357, 5B10N87358 or 5B10N87359 before ordering. Ensure the voltage reads 11.58V to avoid a mismatch.

Questions about this item

Does the L17L3P61 battery fit the IdeaPad 320S-13IKB chassis without modification?

It replaces part numbers 5B10N87357 5B10N87358 5B10N87359 81AK and matches the 11.58V 36Wh specification used in the 320S-13IKB, Yoga 720-12IKB, Flex 6-11IGM and Xiaoxin 7000-13 series.

Which screw or latch step do installers most often miss when swapping the L17L3P61?

After removing the bottom case screws, the battery connector must be unplugged before lifting the old pack; skipping that step risks damaging the 11.58V 3108mAh cell ribbon cable.

What indicates the L17L3P61 needs replacement beyond normal ageing?

If the 36Wh pack no longer holds charge for a typical session, shows swelling, or the system reports a permanent battery fault, the Li-Ion cells have reached end of life.
